UNITED STATES PATENT OFFICE,

JOHN P. THOMPSON, OF FALL RIVER, ASSIGNOR OF ONE-HALF TO THE IVHITIN MACHINE IVORKS, OF WI-IITINSVILLE, MASSACHUSETTS.

MACHINE FOR AND METHOD OFCARDING WOOL, 840.

SPECIFICATION forming part of Letters Patent No. 443,416, dated December 23, 1890. Application filed November 8, 1387. Serial No, 254,620. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN P. THOMPSON, of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Machines for and Methods of Carding ool, 850., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to a method of and a machine for carding cotton, wool, or other fibrous material.

The objects of my invention are to render the carding-machine more efficient and to improve the quality of the carded lap or sheet produced from the machine.

To the aforesaid purposes my invention, briefly stated, consists, essentially, in introducing into the carding-machine pressing or packing mechanism for pressing and packing the loosened fiber into a smooth sheet or lap, and, further, the invention consists in the step of packing the fiber in the operation of carding.

In order that my invention may be fully understood, I have illustrated in the accompanying drawings and will proceed to describe the best form thereof so far devised by me, with the knowledge that the same may be variously modified, without, however, making a substantial departure from the spirit of my invention.

In the accompanying drawings, Figure 1 is a side View ofa portion of a carding machine or attachment embodying my improved packing mechanism, and Fig. 2 is an enlarged detached view of the packer with the rock-shaft shown in section.

In the said drawings, like numbers of reference designate corresponding parts throughout.

Referring to the drawings 3, designates the machine-framing, t the carrier-cylinder, and 5 the co-operating doffer-roll, from which the fiber is doffed by means of the vibrating doffer or comb 6, which is fast upon the rockshaft 7, operated by means of the arms 9 and 10, shaft 11, pulley 12, hand 13, bandwvhcel 14, and the shaft 15. The rotary feed-rolls 16 receive the lap or sheet coming from the doffer and the packer, which will now be described, and may feed the same to a main cylindeit (Not shown.)

The vibrating packer 17 consists in a loose sleeve 18, having the internal raised bearingridges 19 for decreasing the friction of the sleeve upon the incased rock-shaft '7, and from the sleeve 18 extend the arms 20, which are adapted to carry the presser-plates 21, having the packing fingers or teeth 22 for manipu- 6o lating the doffed fleece as it passes thereunder from the dotfer to the feed-rolls 16. The packer is vibrated by means of the rigid bar 23, extending from the sleeve 18, and provided with slot 24, through which extends the stud 25 on 6 5 the upper end of the connecting-rod 26, connected eccentrically with the disk 27,-receiving its motion from shaft 28, which may be driven from the shaft 15 or any other convenient rotating shaft. The packing-bed 29 ex tends underneath the packer 17 from the dotfer to the feed-rolls.

It will now be obvious that, as the fieecy fiber is delivered from the doffer (5 and comes under the action of the vibrating packer 17 the loosened fiber will be worked into a smooth and somewhat compact sheet or lap by virtue of theblows of the packer, and the same will be introduced to the feed-rolls in this packed or pressed condition, and thence to the main cyl 8o inder, which is not shown.

By virtue of my improvements I greatly i1nprove the efficiency of the carding machine and produce a superior quality of lap.

Having thus described my invention, I claim 8 5 as new and desire to secure by Letters Patcut- 1. The combination, as hereinbefore set forth, with the doffer-roll, of the doffer for doffing the fiber from the said roll, and a vi- 9o bratin g packer constructed to press the dofifed fiber into a smooth sheet or lap, the bed 29, and feed-rolls 16, substantially as and for the purpose herein described.

2. The combination, as hereinbefore set 5 forth, with the carrier-cylinder and the doffer-roll co operating therewith and the feedrolls, of the doffer for the said roll, and the vibrating packer constructed to press and pack the fiber doffed from said roll, and the 10c looting the partially carded and cleaned fiber after it has passed the licker-in of the cardingnnaehine, packing and compressing the fiber so collected inio a sheet or lap, and then feeding the lap so packed and compressed to the main caMing-cylinder, as described.

JOHN P. THOMPSON.
